AUTOMATIC MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 443,909, dated December 30, 1890.

Application filed September 24, 1890. Serial No. 365,975. (No model.)

To all whom, it may concern:

Be it known that I, JAMES MICHAEL FAR- iiER, engineer, asubject of the Queen of Great Britain, residing at Esher Villa, Belgrade Road, llampton-on-Thames, in the county of Middlesex, England, have invented an Automatic Musical Instrument; and I do hereby declare that the following is a ful1,clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to that class of musical reed instruments in which a perforated endless traveling band is employed in connection with a concertina-hellows to govern the passage of air to the vibrating reeds; and the invention consists in a simple device for giving mot-ion to the feed-roller in one direction only, in means wherebyasingle scale of reeds is caused to produce the effect of a double set during the expansion and contraction of the bellows, and in various details of construction hereinafter more fully described; and in order that the said invention may be more clearly understood and readily carried into effect I will proceed, aided by the accompanyin g drawings, more fully to describe the same.

In the drawings, Figure l is a longitudinal section, taken on the line 1 1 of Fig. 3, of an instrument constructed according to my inventlon. F1g.2 is a longitudinal elevation thereof. Fig. 3 is an under side view thereof. Fig. 4 is a transverse sect-ion taken on the line 2 2 of Fig. 1, and looking toward the left. Fig. 5 is a similar view looking toward the right. Fig. 6 is a portion of Fig. 1, but drawn full size. Fig. 7 is a side elevation thereof. Fi 8 is an end elevation thereof. Fig. 9 is an under side view thereof with part of the cover of the music-box broken away. Fig. 10 is a side view of the cover of the music-box and connected parts separately. Fig. 11 is an end view thereof, and Fig. 12 is an inside view thereof.

In the several figures like parts are indicated by similar letters of reference.

a (4* represent the bellows, a a represent the end caps thereof, and 1) represents a valvebox, which is located centrally of the bellows and divides it into two parts a a*, so as to constitute a double-acting instrument, and the outer ends of the caps to a* are conneotcd together by means of bars a fixed thereto, but not to the central valve-box b, and formed with long slots o thereon.

At the sides of the valve-box b are provided projections b*, which travel in the slots ct of the bars a2, in order to guide the valvebox Z) in its movements, and to these projections 1) are fixed the innerends of two bars or rods 1), which pass through guides a upon the bars a and extend beyond the end cap a* of the bellows (0*, and are there connected by a cross-head b pivoted thereto at I) for convenience in use, and to which is attached one of the usual loops or straps so, under which is placed the hand of the performer, the other of such loops or straps 00- being attached to the end cap a of the bellows a at the opposite end of the instrument. By this arrangement of parts the central valve-box b may be moved to and fro, alternately compressing and expanding the bellows a co The valve-box Z) is divided into twoparts b b** by a horizontal partition if, and to the lower part b** thereof is fixed the music-box If, within which is located the reed-chamber c, which is fitted with a single scale of reeds c and is open to the lower part If of the valve-box b.

The bellows o communicates by a way I) with the lower part b** of the valve-box 1), while the other bellows a communicates there with by a way or conduit b and valves 1) 11 are employed to close the airways b If during the compression of the bellows a a* and to open them during the expansion thereof, while the waste air is exhausted from the bellows during their compression through other valves b which close during their expansion. Air will thus be drawn through and will sound those of the single scale of reeds that are not covered by the endless perforated band f during the movement of the valve-box b and bellows a a* in either direction and during the consequent expansion of either of such bellows.

Motion is given to the roller (I, which feeds forward the endless perforated band f of music across the wall of the reed-chamber c, by the following means: The feed roller d is provided with necks or axes of motion d, which are mounted in bearings formed in IOU the walls of the music-box b and one of such axes passed through the wall of the music-box b and has fixed thereon a pulley (1 formed with double grooves (1 d therein and at intervals the feed-roller d is fitted with india-rubber bands d which enable the :roller (Z to obtain a proper grip of the endless band f of paper, as hereinafter described.

To a stud upon the end cap a of the bellows a is attached one end of a cord e, and this cord e thence passes over a guide-pulley e, mounted upon a stud 52, carried by the end wall of the valve-box b, thence over and completely around one division (1 of the double grooved pulley d thence over an idle or guide pulley (2 mounted upon a stud 6 fixed to the music-box b thence under and around the other division (1 of the grooved pulley (l and thence over a stud to a cleat e upon-the cap a'* of the bellows of. By this arrangement of p rts the cord e, during the inward movement of thecap a uponthe compression of the bellows a will be slackened and will therefore slip upon the groove (1 of the pulley d while upon the simultaneous outward movement of the cap a and corre sponding expansion of the bellows a the cord will bind upon the groove d of the pulley d and rotate the feed-roller d. The same action will take place upon the expansion of the bellows a, but in that case the'cord will bind upon the groove (W, the act of drawing the corde off the pulley d causingiit to bind thereon, so that whichever bellows a or 01* is expanded the feed-roller (1 will be rotated, and by reason of the direction in which-the cord e is passed around the groove of the pul v ley at the feed-roller (1 will always travel in one direction.

The music-box b is formed open at its sides in order to allow of the passage of the endless band f of music, and it is perforated 'upon its under side to permit the musical sounds to issue therefrom without obstruct-ion.

The bottom or cover 12 of the music-box b I form readily detachable therefrom to allow of the end-less band fbeing placed in position, and the cover is provided with fixed hooks b to engage corresponding studs b upon the music-box b and the music box b is provided with pivoted hooks o: catches b to engage corresponding studs b upon the cover Z), by which means the cover is capable .of being readily attached to the lltI'lSlC-bOX b orof being detached therefrom when desired.

Upon the inside of the cover I) of the music-box b is mounted in bearings with capability of revolution a roller b which impinges upon the rubber rings (1 of the feedroller (1, and thus causes such roller d to obtain a proper grip of the endless bandf, and the endless band f is guided in its movements by projecting ribs or flanges b fixed upon the outer Wall of the reed-chamber o.

By arranging the means for giving motion to the feed-roller d upon the exterior of the instrument, I am enabled more readily to adjust the same'than heretofore.

Having now particularly described and as certained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. An automaticlmusical instrument formed with a central valve-box b, a separate bellows a (.t* upon each side of such valve-box, bars a connecting theend caps aa of such belvalves for the admission of air to the bellows f and for the exhaustio'nof such air, substantially as hereinshown and described.

.2. In an automatic musical instrument, the

combination of Iacentral valve-box b, a separate bellows a a* upon each side of such val vebox. bars at, connecting the end caps a a'* of :such bellows, Ja cross-head 11 connected by bars b" with the valxe-box b,-a scale of muisical reeds 0' arran ed within a reed-chamber located within a music-box b suitableways closed by valves for the admission of air tothe bellows and for the exhaustion of such air, a feed-roller d, provided with a double-grooved pulley d guide-pulleys 6' 9 and a length of cord e, passed aroundsuch pulleys and at each end fastened to the endcaps of the instrument, substantiallyas here-' in shown and described, and for the purpose stated.
